| Abstract: | Aggregate Stability and Penetration Resistance of two Normal and Limed Soils To investigate the meliorative effect of liming, the aggregate stability (determined by wet sieving and sedimentation) and the penetration resistance (by a previously described method (Becher 1973 a) of unlimed and limed samples of two field experiments on a Brown Earth-Pseudogley and a Humic Pseudogley were determined. Penetration resistance decreased with decreasing water suction, but it did not show significant relation to liming. Aggregate stability was increased by liming on the Brown Earth-Pseudogley but was lowered on the Humic Pseudogley, while penetration resistance was only influenced in some cases. The behaviour of the Humic Pseudogley was explained by its exceptional high organic matter content (5–6%). |
